We found that optimal π-π stacking, as represented and highlighted on Figure 10C, could be achieved only when AChE586-599 β-sheets have the same sides facing each other ('face-to-face') and the orientation of the sheet edges facing up ('up-up').
Three types of graphite nanofibers (GNFs), with varying orientations of the graphene sheets (herringbone, platelet, and ribbon), were used as catalysts for the gas-phase oxidative dehydrogenation of ethanol to acetaldehyde and ethyl acetate in the presence of oxygen.
Cracking was first induced, and then repairs were performed using an epoxy injection with varying orientations of the AFRP sheets, followed by testing of the beams to failure.
The orientation of the blank sheet rolling direction and the combination of the blank sheet materials has significant influence on the deformation behaviour.
The images show the seeds as they pass through the laser sheet, and the SVR may be difficult to identify in some panels because of the orientation of the laser sheet with respect to the axis of the SVR.
A growth model has been described proposing that atomically thin graphene sheets result from a balance between deposition through surface diffusion and etching by atomic hydrogen, and that the observed vertical orientation of these sheets results from the interaction of the plasma electric field with their anisotropic polarizability.
Molecular dynamics simulations involving the sub-nanoscale interface reveal a most favourable set of temperature independent orientations of the monolayer graphene sheet with an angle of ∽15° between its armchair direction and [010] axis of the silicon substrate.
A very systematic change in morphology and orientation of the MDO sheet was observed with changing draw ratios, while the degree of crystallinity did not change.
Moreover, the vertical molecular orientation of the extruded sheet sample is responsible for unique mechanical anisotropy; the fracture occurs along the transversal direction.
Here, θ is an angle between the long axis of the striped domains and the edges of the contacts that define the physical width of the accumulation channel, W; θ can be easily controlled by changing the orientation of the Mylar sheet during drop-casting TIPS-pentacene solution.
